Retreat by PM Cameron 'shows the strength of DUP hand'
The DUP has pointed to its potential influence over the Conservative Government after the controversial 'English votes for English laws' proposal was postponed until September.
Both Government whips and potential Tory rebels were reportedly in touch with the eight DUP MPs amid speculation Prime Minister David Cameron was facing an embarrassing defeat over plans to exclude Scottish MPs from certain votes.
DUP deputy leader Nigel Dodds said: "With a very slim majority, the Government is well aware that DUP MPs will only support proposals which strengthen the Union."
The North Belfast MP said the Government had attempted to bring through constitutional changes by use of House of Commons standing orders.
"Proper legislative changes, brought forward after detailed consideration, is how constitutional change should be managed, not rushed changes to standing orders," he added.
Commons leader Chris Grayling said that a Commons vote on the issue will not be held until at least September following anger from Tory backbenchers along with a co-ordinated effort by Labour and the SNP to defeat the plans, which will give English MPs an effective veto over English-only issues.
